AR15 .223 1/2"x28 Tanker 50 Style Stainless Steel Muzzle Brake

The muzzle brake you sent is not the one I ordered You sent a 30 cal 5/8" thread instead. I kept it because I can use it on another barrel. I felt that the workmanship or inspection was rather poor. The bore had burrs sticking into the path of the bullet that should have been removed before shipping.
